VALVE.

Specification of Letters Patent.

Patented J une 21', 1910.

Application filed August 20, 1909. Serial No. 513,827.

To all whom 'it may concern:

Be it known that I,"l`noims I). LONG, a citizen of the United States,anda resident. of Barherton, in the county of Summit and State of Ohio,have invented a new and Improved Valve, of which the following is afull, clear, and exact description.

Among the principal objects which the present invention has in View are:to provide a mechanism for rapidly opening and closing valves in theemployment of which the lateral strain upon the valve stem is minimized;and to provide a mechanism for rapidly opening and closing valves whichis simple, durable and eiicient.

Oneembodiment of the present invention is disclosed in the structureillustrated in the aeco'mpanying drawings, in which like characters ofreference denote corresponding parts in both the views, and in which-Figure 1 is a side elevation of the device shown in its application toan ordinary gate valve; and Fig. 2 is a vertical section of theeccentric wheel and yoke upon which the same is mounted.

The present construction may be applied to all of the usual forms ofvalves, being equally applicable to all straight lifting valves andadvantageous in that the power applied for lifting or depressing thevalves is not only equally applied but applied with increased power.

The valve stem 3 is bifurcated at the upper end by forming a slottherein, using any suitable means therefor. Extended from suitableperforations formed in the bifurcated ends is a pin 4. The in 4 is heldin place after bein extende Y bifurcated ends o the stem 3 by means of acotter 5.'

A yoke 6 is provided with 'a ring-like body portion 7 which fits thebonnet of the valve snugly and is heldin position thereon by means of ajam nut 8. Threadably mounted upon the screw threaded extension of thebonnet is a cap nut 9, through a perforation in the center whereof thestem 3 is passed. The open construction of the yoke 6 permits the rapidmanipulation of the nuts 8 and 9 when seating the same to hold the yokein position. The upper end of the yoke is parted to form verticalextensions 10, 10 through a perforation in which is passed a screwthreaded pivot bolt 11. The

bolt 1l is provided with a screw threadedl through the end held inthreaded engagement with a screw nut, while the other extension .p issmooth bored and adapted to receive the impingement of the head of thebolt 1l.

The bolt 11 hasI pivotally mounted thereon a disk l2 the rotary centerwhereof is eccentric to the circumference of the disk, as shownparticularly in Fig. l of the drawings. Concentric with thecircumferei'icc of the said disk is a semi-eircular slot 13 formed inthe said disk to receive the pin 4 which is passed through the sides ofthe upper end of the valve stem 3. The disk 12 has fixcdly mountedthereon and preferably extended in line with the rotary center of thesaid disk. a handle 14. i

In mounting the yoke G, the disk li). and parts connected therewith,upon a valvethe stem 3 whereof is bfurcated or slotted and provided withthe pin 4the disk l2 is placed in position after the yoke 6 has beenfirmly seated upon the valve. In placino' the disk 12 in position it isfirst extende through the vertical extensions l10, 10 and into the slotformed in the upper end of the stem 3, when the pin 4 is extendedthrough the perforations provided. in the end of the stem 3 and throughthe slot 13 formed in the disk 12. The perforation in the disk 12 uponwhich the said disk is to be rotated is then alined with theperforations formed in the vertical extensions 10, 10 and the pivot bolt11 is extended through the said perforations being threadably engaged inone of the said extensions 10, 10. When the bolt 11 is snugly set up tothe extension 10 the device is in position to be operated. f'

The perforation upon which the disk 12 is rotated is, by preference,disposednsubstantially in line with the ends of the slot 13. It isplaced so that the ends of the slot are unequally distant from the saidperforation, whereby the pin 4, when contained in the said slot, isdrawn to or forced from the bolt 11 by the rotation of the disk 12 uponthe said bolt 11. The distance between the disposition of the one end ofthe slot from the bolt 11 when in line between the stem 3 and the bolt11 and the distance between the other end of the slot and the bolt 11,equals the extent of the action of the stem 3 and valve connectedtherewith.

In its operation it is provided that the handle 14 should be held in thedepressed position shown in Fig. 1 of the drawings when the valve 15 isclosed. To fully open the valve the handle 14 is raised to the osi.-tion shown in dotted lines in Fig. l ot the drawings. In this action onthe part of the handle 14 the disk 12 and pin 4 on the stem 3 hastraveled vertically in a line coincident with the extensions of the yokeG, the pin 4 sliding freely in the slot 13. At any point intermediatethe fully closed or open position of the valve 15 the handle may bearrested and held by upsetting the bolt 11 to bring the extensions l0,10 in holding contact with the disk 12. Further, when the said valve isby this device placed in full open or closed position it may be thereheld by upsetting or tightening the said bolt 11, insuring the positionof the valve against Vibration or accident.

Having thus described my invention7 what I claim as new and desire tosecure by Letters Patent is l l. A valve comprising a supporting frameformed upon the bonnet of the said valve; a cam-like memberrotatablynmounted upon said frame; means connecting the stem of saidvalve to the cam surface of said member to reciprocate `said valve stem;and means for rotating said member.

2. A valve, comprising a yoke-like attachment adapted to tit upon thebonnet of the said valve; a cani-like member rotatably mounted upon saidattachment; means for connecting the stem of the said valve to the camsurface of said member; and means for rotating said member.

3. A valve, comprising a yoke-like attachment adapted to fit upon thebonnet of the said valve; a disk rotatably mounted on said attachment; acam slot formed in said disk; means for connecting the stem of saidvalve with said's'lot to slide therein; and means for rotating the saiddisk.

4. A valve, com rising a yoke-like attachment adapted to t upon thebonnet of the said valve; a disk rotatably mounted between the ends ofsaid attachment; a slot formed in said disk eccentric to the rotarycenter thereof; means for connecting the stem of said valve with saidslot to slide therein; and means for rotating the said disk. l i' 5. Avalve, com rising a yoke-like attachment adapted to it upon the bonnetof the said valve; a disk mounted between the ends of said attachmenteccentric to the structural center of said disk; a slot formed in saiddisk concentric with the structural ccnlter of said disk; means forconnecting the stemof said valve with said slot to slide therein; andmeans for rotating the said disk. i

Yof said attachment eccentric to the structural center Ot' said disk; aslot formed in said disk concentric With the structural center of saiddisk; means for connecting the stem of said valve with said slot toslide therein; means for rotating the said disk; and means for lockingthe said disk immovably on said attachment. v

In testimony whereof I have signed my name to this speciication in thepresence of two subscribing Witnesses.
